Two very contrasting ones for this week.
First the very celebral RSA animate talking about education. Very clever. It's here. Check out there other stuff as well.
On the other end of the spectrum check out the technoviking. Don't mess with him, he is apparently an internet hero. The original is here but you need to click on the red speech bubble on the bottom right to remove the red layer (it will make sense when you get there)
